SIQE DOOR.

Application led 'July 12, 1924. Serial No. 725,853.

This invention relates to side doors and more particularly to fabricated metal, side doors for use on box cars.

It is a general object of this invention to provide an improved, metal, box car door.

It is another object of this invention to provide an improved fabricated metal box car door, the body of which is formed of fiat plates reinforced at their meeting edge by offset flanges.

A further object of this invention consists.

in the provision of box car doors fabricated from'several flat sheets of metal having olfset flanges at their meeting ed es and being provided with vertical edge sti eners riveted to the sheets of the door in two planes at right angles to each other.

For a complete understanding of this invention, reference should be had to the following speciication taken together with the accompanying drawings wherein:

Figure 1 is a partial elevation of the side of a box car showin@ the improved type of door according to this invention in position;

Figure 2 is a vertical section through the door audits supporting parts on line 2-2 of Figure 1, but shown on a much larger scale;

Fi ure 3 is a partialhorizontal section of the orward meeting edge of the door and frame, taken on line 3-3 of Figure 1, but shown on an enlarged scale;

Figures 4 and 5 are partial horizontal sections on lines 4-4 and 5-5 respectively of Figure 1, shown on the same scale as Figure 3; and

Figure 6 is a line 6-6 of Figure 1. f

As Iclearly illustrated in Figure 1, abox car door constructed according to this. invention is adapted to be appliedto any conventional box car constructed of wood or steel. The car 10 shown in the figure is constructed of steel and is provided near its lower edge with the track'll upon which rollers-mounted on the door are adapted to travel, and

. with the bumpers or'door' l'stops 12`to limit the. opening movement of the door.

.The door '13. is .constructed mainly of three'pressed steel Iplates orpanels 14, 15 and 16 riveted together alono' their Vhorizontal meeting edges and reinfp Y' vertical edges by means ofthe vertical stif feners 17 and 18 securely riveted to anges on the door plates. The upper edge of the plate14-and the llower edge of the plate 16 are reinforced by horizontal stieners, all of partial vertical section on.

orced along theirfmore fully in detail. v

The main plates or panels 14, 15, and 16 of the door are offset outwardly at their meeting edges 19 and 20 as shown more clearly in Figure 2, where it will be noted that the plates are first bent upward nearly at which parts and members will be described right angles, forming the substantially horii sisting bending or buckling in the direction' of the length of the panels. The lower edge 23 of the lower panel 16 is retained in its normal flat form and reinforced by the Z-bar 24 having its one liange 25 securely riveted to the inner face of the panel 16 lwith the lower face of the web in a line with the lower edge of the panel and extending inwardly therefrom so that the lower flange 26 of the Z-bar forms in effect an inwardly offset guide flange for a purpose to be hereinafter described. The upper edge of the upper late 14 is adapted to be reinforced by the -bar 27 having its upper flange 28 securely riveted to therouter face of the'flat portion of this panel. Theupper edge of this panel Y pressed outwardly to form the'short vertical vcorrugations 30, the summitsa of which are securely riveted to thev flange 29,-the material to form these corrugations being pro- "vided-.b'y allowing the upper edge of the downwards, as shown at 31.

yreference to Figure 6, this construction will be clearly understood.

The rear vertical edge of the door is rein- 'l lforced by the distorted` angle bai' 32, a .por-

tion of one leg of which is bent inwardly to form an obtuse an le with the remainder; The end portions o the panels 14, 15, `and 16 between their offset horizontal meeting edges are provided with right' angled outwardly extending flanges 33 which are securely riveted to the' leg 34 of the vertical stiffener 32. The leg 34 of this stiffeneris of such a width. that the front, right-angled flange 35 of this angle rests upon the oifset overlapping joints of the several panels, and at these points is securely rivetedthereto by the rivets..;36 as best shown in F1gure 5. The vforward or leading edge of the panels 14, 15, and 16 is treated in exactly the same manner as just described in connection with the rear edge with the exception that the vertical stifl'ener member is a Z-bar instead of an angle and has its web 36 riveted to the right angled flange 33 at the end of the panels and its flange 38 riveted to the over-v lapped portions of' the panels The lflange,

39 of' the Z-bar extends substantially in the same plane as the main part lof the door,.

as clearly shown in Figure 3 for a purpose to be later described This method of constructing and fastening the vertical stiffeners of the main panels of the door results in an unusually` rigid structure Riveting the vertical stifl'eners to tuhe panels by rivets arranged in two planes at right angles to each lother eliminates any tendency for the vertical edge stieners vto turn about a vertical axis, thus preventing distortion or displacement of these members when the door is violently slammed either againstthe stops 12 when in open position or against the door posts, which will y.be later described, when in a closed position. i

As shown in Figure 1, the rollers 40 which are adapted torun upon the track l1 are mounted in castings which are securely riveted to the lower corners of the panels 16, the upper flange of the lower stifl'ener 25 and the webs ofthe vertical edge stiffeners, thus serving not only as housingsy for the rollers butas ties for the horizontal and vertical edge stiffen'e'rs of the door.y As shown in Figure 2, the track 11 may conveniently be a channel member arranged with the web uppermost and support/ed frm the longitudinal beams42 of the`car by means of the brackets 43. It. is spaced a slight distance from these-beams-42 in order to provide a channel in which the lower flange 26 of the lower edge stifi'eneris I adapted ,to run in order to guide the -rollers and to prevent them from moving outwardly from the car and running oft' of the track. This flange 26 also serves in a measure as a weather strip closing the lower edge of the door. While a bottom supported door has been disclosed it will be readily understood that the invention may be applied -equally as well toaJ top hung door.

The', upperv edge of the door is guided and prevented from lifting 'by means of the Z- bar 44 securely-riveted; to the u per struc' ,ture ofthe bar and .having ,the `yertacal flange 45 which overhangs the vertical flange 28 of the upper horizontal st-ifener of the the manner in which the rear edge of the door is rendered water-tight and prevented from rattling when closed. In these figures, tothe outer metal side 46 of the car is shown bolted the door post 47 and having interposed between the siding and the post the vweb of the Z-bar 48 to which the door post is also secured by the bolts 49 in addition to those throughthe siding and having its outer flange 50 bent parallel to the web as shown at 51 in order to provide an edge 52 for the distorted leg of the angle member 34 on the edge of the door to press against. The bent portion of this angle member being at an angle facing' toward the dierction of movement of the door will ride over the edge 52 and tend to draw the car door closer to the side of the ear, thus which will keep out ram, and wind nov matter in moving. Figure 3 discloses in a similar manner a method of'closing the forward edge of the door. In this case to the sidingrr46 of the car is boltedthe door post 47 and has interposed between these two members the. Z- bar 48 having a shortened outer flange 53 to which is riveted the one :ll-an e of a smaller Z-bar 54 having its` outer bent almostparallel to the lweb* to provide ,a channel intdrwhich the flange 39 of the vertical stiene' 37 ofthe car door` may lit to thus form a weather tight joint. i y

In order that the door may besecurely locked in a closed position, there is provided the hasp 56 pivotally mounted upon the eye 57 having theflanges 58and59 riveted in two planes to the edge still'ener. 37 of -the car door. The offset bracket 60 mounted upon the side 46 of the vcar has integral therewith a stationary speed 61 over which the slot 62. in the hasp 56 is-adapted to be passed to retain the hasp. in4 position. Suitable holes .are provided' for the-insertion of the wires ofthe door` seal. i

Erom the foregoing description it will be seen that this invention contemplates the vwhich direction the car may be provision of the novel, all-metal, car door` While but a single'-einbodiinentgoffthis in'-l ange 55 tionjas expressed in thefollowing claims:
